HOREX is Mantle8’s proprietary exploration platform that integrates multiple geophysical, geological and geochemical datasets to generate 4D images of active natural hydrogen systems in the subsurface.[6] The technology is designed to map hydrogen generation zones, migration pathways, traps and sealing units with high spatial and temporal resolution, providing a basis for ranking prospects and targeting drilling locations for natural hydrogen exploration campaigns.[6]

Geophysical surveys in this context involve acquiring and interpreting subsurface data—such as seismic reflection, passive seismic, gravity, magnetics and sometimes electromagnetic signals—to characterise the geology and structures that control natural hydrogen generation, migration and trapping.[1][3] In the Comminges permit, Mantle8 has begun geophysical campaigns across the full 739 km² area to build a detailed picture of subsurface hydrogen dynamics before selecting drilling locations.[1]

Hydrogen occurring naturally in the Earth's crust and mantle, produced through inorganic chemical reactions rather than from fossil fuels. It is extracted directly from the ground without requiring energy-intensive production processes.
